Outstanding = is a pending authorization not yet settled.
Matched = a settled authorization (parameters matched..amount, mcc...)
Cleared = credit
Dropped = authorization dropped
Billing Amount Out of Range - a settlement for an authorization didn't
match due to amount.
No Matching Required - usually a credit from a merchant/atm or a
reversal
